Embodiment 1

[0023] The invention provides a photoelectric trigger alarm device, see figure 1 , figure 2 , which shows a preferred embodiment of the invention. Described warning device comprises telephone set 1, telephone line 2, the full-bridge rectifier 3 that is connected with described telephone host 1 by described telephone line 2, optocoupler 4, signal processing output unit 5, the The front stage is connected to the full bridge rectifier 3 , and the rear stage is connected to the signal processing output unit 5 .

[0024] In order to prevent the device of the present invention from affecting it when intervening in the existing telephone system, and also to prevent the telephone system from affecting the operation of the device of the present invention, the device of the present invention uses a photocoupler 4 as an intervening device between the telephone system and the device of the present invention. unit. The optocoupler 4 is a four-port device packaged in a compact structure...

Embodiment 2

[0039] The difference between this embodiment and the above embodiment is that the alarm device also includes a central processing unit to replace the signal processing output unit 5, and the central processing unit simulates the function of the signal processing output unit 5 through programming.

[0040] The signal identification module 303 of the central processing unit identifies the action 301 of picking up and hanging up the phone, and performs overtime judgment by the timeout judgment module 305; During the set time, the output module 306 outputs an output signal Yx corresponding to the number of times the phone is picked up and hung up, and the output signal Yx sends an alarm signal by controlling the alarm terminal device connected to the signal output pin.

[0041] In this embodiment, through the signal conversion of the photocoupler 4 , the signal recognition module 303 in the central processing unit recognizes the pick-up and hook-up action of the telephone set 1 . ...

Abstract

The invention relates to a photoelectric triggering type warning device. The warning device comprises a telephone set, a telephone circuit, a full-bridge rectifier, a photoelectric coupler and a signal processing and outputting unit, wherein the full-bridge rectifier, the photoelectric coupler and the signal processing and outputting unit are connected with a telephone host through the telephone circuit. Through the warning device, usage convenience of similar help or assistance asking devices is kept, and meanwhile the problem that as new equipment is additionally arranged, desktop space which is already quite cramped is further occupied is solved. In addition, because the telephone set is large in size and is an article which is used frequently by an old person in daily life, the warning device can be fumbled more easily by the old person compared with a specialized device when the old person is in a crisis; accordingly, the warning device can effectively bring the efficiency of the similar warning products into full play in an emergency.

Description

technical field [0001] The invention relates to a signal output device, in particular to a photoelectric trigger alarm device. Background technique [0002] With the advent of the elderly society, a large number of emergency alarm products for the empty-nest elderly have emerged in recent years. Among them, a help button similar to "Push to Talk" is more common. Its form is a special button, placed on the old man's desk or bedside table, using wired or wireless transmission. When the old man needs external assistance, he can press one or one of several buttons on it, and the device can output the pressing action to the external device, so that the external device can send an alarm signal locally or to the outside in the form of sound and light, so as to realize external assistance. Call for help or help. [0003] The problem with existing approaches, however, is that a dedicated button takes up the already rather cramped countertop space of a desk or nightstand. At the s...
